Abstract

In recent years, pedestrian detection is a hot research topic in the field of computer vision and artificial intelligence, it is widely used in the field of security and pedestrian analysis. However, due to a large amount of calculation in the traditional pedestrian detection technology, the speed of many systems for pedestrian recognition is very limited. But in some restricted areas, such as construction hazardous areas, real-time detection of pedestrians and cross-border behaviors is required. To more conveniently and efficiently detect whether there are pedestrians in the restricted area and cross-border behavior, this paper proposes a pedestrian cross-border detection method based on HOG (Histogram of Oriented Gradient) and SVM (Support Vector Machine). This method extracts the moving target through the GMM (Gaussian Mixture Model) background modeling and then extracts the characteristics of the moving target through gradient HOG. Finally, it uses SVM training to distinguish pedestrians from nonpedestrians, completes the detection of pedestrians, and labels the targets. The test results show that only the HOG feature extraction of the candidate area can greatly reduce the amount of calculation and reduce the time of feature extraction, eliminate background interference, thereby improving the efficiency of detection, and can be applied to occasions with real-time requirements.
